7.Can this kit repair scratches on tempered glass?

Answer: Sure, it can. In fact, it is easier to repair scratches on tempered glass. During repair, grinding makes temperature at the grinded area rise gradually. Untempered glass may burst when heated to a certain degree. But tempered glass won’t burst because it is more tolerant towards the temperature difference between cold and hot. Thus, we say it’s easier to repair tempered glass. Pay attention to temperature control when you repair untempered glass. Stop operation before glass is too hot to touch. Do not continue until glass temperature drops to room temperature.
